What came first, the vampire or the bat?

A vampire bat.

Sadly, bat populations are declining worldwide at an alarming rate.

Biologists believe that this is because of misconceptions about bats, communication towers and turbines, White Nose Syndrome, a fungus which has appeared in 2006 and has wiped out a lot of the hibernating bats in the northeast, and property development.

“Most bats living in Virginia prefer to roost in mature or dead trees or in caves. However, many bats are forced to take up residence in human dwellings or other buikdings due to loss of these types of habitat,” reported Bat World of Hampton Roads.

“Also, human disturbance in caves during the winter can force bats to burn up energy during their normal hibernation cycle, causing the bats to starve to death before insect populations re-appear in the spring and provide a food source.”

Because of these factors, half of all the bats in the U.S., and 60 percent of bats in the world, are listed as rare, threatened, or endangered.

Three bats in Virginia, the Gray Bat, Indiana Bat, and Virginia Big-eared Bat, are federally endangered, while the Rafinesque's Big-eared Bat, is state endangered.

Residents of Virginia are encouraged to make or buy bat houses and place them in the yard.

Remember, when building and/or installing a bat house, specific requirements should be met - such as the dimensions and location (depends on sunlight) - in order to attract bat colonies.

“Bat houses are a perfect way to get involved in conservation. A bat house in your backyard provides bats with a much needed, safe place to live,” Bat World of Hampton Roads reported.

“They will also do you the return favor of eating insects around the area.”
